If you have a WordPress blog and allow comments then you know spam can be pain. It can get very time consuming having to go through the spam queue and sort out the real comments from the spammy ones. Luckily it’s fairly easy to keep your blog spam-free with just a few simple steps.

1. Use Plugins

I’ve tried a few different plugins over the years, and these three have been working really well for me. Also, the WordPress Codex has a guide on how to deal with spam which includes a few recommended plugins. Either way you can’t go wrong with a plugin or two.

G.A.S.P. adds a checkbox to your comment form for your users to verify they are not a spammer. It’s a lot more convenient than using CAPTCHAs, and it does the trick at helping prevent spammy comments.

2. Close Your Comments

In Settings > Discussion there’s an area under Other comment settings where you can close comments on posts after a certain period of time. Spammers tend to target older posts, so enabling this feature will definitely help. I have mine set to 60, but you can do whatever amount of days is comfortable for you.

3. Use a Comment Blacklist List

If you go to Settings > Discussion there is an area called Comment Blacklist. Any words you list here will comepletely blacklist a comment containing those words. If you’re not sure which words to put in you can use a premade list to start.

The good thing about this is by implementing a list of common blacklist words it reduces an amazing amount of spam; however be warned! The downside is if someone posting a legitimate comment uses one of those words their comment will be immediately deleted, no notification or anything.

Since implementing the blacklist in conjunction with the other plugins and keeping my comments closed I’ve seen a major decrease in spam on my blog. What methods do you use? Got any recommended plugins?
